Problems solved by technology

Secondary processing of parts that cannot meet the requirements
[0007] In the existing technology, it is difficult to ensure that the sliding friction between the telescopic shafts meets the design requirements through size matching
However, the combination of adaptation and tension gauge is used to ensure the design requirements. The operation is cumbersome, which greatly reduces the work efficiency.

Embodiment Construction

[0039] refer to Figure 5 , the lower transmission shaft wear test bench in this figure has installed the lower transmission shaft 4 to be tested. The lower transmission shaft wear test bench includes: base plate 12, fixed support 8 fixed on the base plate 12, sleeve pipe support 9 fixed on the base plate 12, cam disc 10 and rocking arm 11 that are rotatably matched with the base plate 12. In this embodiment, three groups of fixed brackets 8 , bushing brackets 9 , and rocker arms 11 are installed on the base plate 12 , and one cam disc 10 can be used to perform wear tests on three lower transmission shafts 4 at the same time. According to actual needs, it is possible to continue to increase or decrease the number of groups of the fixed bracket 8, the casing bracket 9, and the rocker arm 11 so as to carry out synchronous tests on different numbers of lower drive shafts 4.

[0040] refer to Figure 8 , the fixed bracket 8 is made of a horizontal plate and a vertical plate to f...

Abstract

The invention provides a lower transmission shaft wear test bench, comprising: a bottom plate; a fixed bracket fixed on the bottom plate, the fixed bracket has a spline head; a sleeve bracket fixed on the bottom plate, the sleeve The pipe bracket has a sleeve; a rocker arm slidingly fitted with the sleeve, one end of the rocker has a spline head, and a slider is installed at the other end, and a load cell is installed on the rocker; it rotates with the bottom plate Cooperating cam plate, the cam plate has a cam and a chute around the cam; the spline head of the fixed bracket, the sleeve, and the rocker arm are coaxially arranged, and the slide block of the rocker arm and the rocker arm are arranged coaxially. The chute of the cam disc is slidably fitted, and when the cam disc rotates, the slider slides in the chute so as to convert the rotation of the cam disc into the linear reciprocating motion of the rocker arm. The invention also provides a method for correcting the size of the lower transmission shaft. The invention improves the detection and correction efficiency of the lower transmission shaft.

Description

technical field [0001] The invention relates to the field of automobile steering system detection, in particular to a lower transmission shaft wear test bench and a method for correcting the size of the lower transmission shaft. Background technique [0002] The car steering device is an important part of the car chassis system. The car steering system is a mechanism used to maintain or change the driving direction of the car. When the car is turning, it is necessary to ensure that there is a coordinated relationship between the steering wheels. By manipulating the steering system, the driver keeps the car in a straight line or turning motion state, or makes the above two motion states switch between each other. Such as figure 1 As shown, the rotation of the steering wheel 1 is transmitted to the lower drive shaft 4 after being assisted by the motor 3 through the steering column 2 , and finally to the steering gear 5 . The steering column 2 is fixed inside the cab, and the...
