Car door frame

Auto parts are the various units that make up the whole car and a product that serves the car. There are many kinds of auto parts. With the improvement of people's living standards, people consume more and more cars, and the market for auto parts is getting bigger and bigger. In recent years, auto parts manufacturers are also developing rapidly.

Engine assembly, filter, cylinder and parts, oil seal, oil pump nozzle, fuel economizer, valve tappet, oil pipe, connecting rod assembly, crankshaft camshaft, bearing bush and connecting rod bush, valve and parts, fuel tank, Pistons, flywheel ring gears, tensioners, belts, superchargers, carburetors, three-way catalytic converters, fuel injection devices, starters and accessories, other engine systems and other automotive engine system accessories.

Walking system Front axle, rear axle, shock absorption system, suspension system, axle housing, axle shaft, balance weight, buffer, rim, wheel hub, frame assembly, automobile tires, agricultural vehicle tires, construction machinery tires and other walking systems And other auto parts.

Body accessories Car shell, car door, car glass, car mirror, license plate frame, seat and accessories, car bearing, armrest, handle, handle, grille, fender, cab and accessories, airbag, car seat belt, glass lift Auto parts such as device, car antenna, wiper, car muffler, car horn, car seal bumper, luggage, luggage rack, extrusion parts, stamping parts, exhaust pipe, other body accessories.

Steering system tie rod assembly, tie rod, tie rod ball joint, center tie rod, steering active arm, steering follower arm, steering gear dust cover, steering gear assembly, steering shock absorber, steering power pump, steering gasket repair Bags, power steering fuel tanks, tie rod adjustment bolts, steering slave arm bushings, power steering tubes, steering knuckles, steering wheels, other steering systems and other auto parts. The tie rod head is also called the ball head to connect the rod. For example, the manual gear is a tie rod head. Its precision requirements are the highest, mainly in terms of force deformation and fatigue resistance.

Braking system brake pads, clutches, friction plates, air compressors, hand brakes, brackets, shaft heads, vacuum boosters, brake shoes, brake pumps, cables, clips, brake assemblies, brake pots, brake chambers, Brake drums, sliders, lifting lugs, control valves, dryers, brake discs, anti-lock braking system/ABS.

1. Engine cylinder sealing test There are seven factors that affect the cylinder sealing, mainly including cylinder wear, piston ring damage, piston wear, valve seat damage, valve guide wear, cylinder gasket damage, valve clearance, etc. question. What are the commonly used diagnostic methods? There are mainly measurement of cylinder pressure, crankcase blow-by, cylinder leakage and leakage rate, intake pipe vacuum, cylinder piston group due to excessive wear and vibration measurement of abnormal noise caused by excessive wear, crankshaft The wear metal in the box is a measure of the particle content. For the measurement of cylinder compression pressure, it is mainly the pressure at the end of compression of a four-stroke engine. Due to the pressure of the cylinder, the viscosity of the engine oil and the cooperation of the cylinder piston group, whether the adjustment of the valve mechanism is correct, the sealing of the cylinder gasket and other factors, when measuring the pressure of the engine cylinder, the cylinder piston group can be diagnosed If the sealing condition of the piston ring, valve and cylinder gasket is good, then the clearance of the valve must be appropriate. 2. Test the soundness of the muffler The muffler is composed of an outer cylinder and an inner honeycomb part. The two parts are combined by mechanical buckle technology due to special environments such as high temperature and vibration. We know that the quality of this process depends on the precision of the design. If the combination is not strong, it will loosen or fall off due to high temperature, vibration and other factors during the use of the car. But what makes us rest assured is that the relevant quality first department has put forward quite strict requirements on this technical aspect. For the actual detection method, the detection tools in the industry use universal material testing machines, and use pressure-resistant disc fixtures to subject the two components of the muffler to the upper and lower relative shear forces. The repeatability error of the measured results should be less than 5%. 3. Interior inspection The interior includes seat materials, interior box decoration materials and adhesives for bonding. Mainly test its safety: 1. Gas harmfulness 2. Flame retardancy.
