Problems solved by technology

Obviously, manual operation is inefficient, poor in repeatability, and does not meet the basic requirements of scientific testing; while the mechanical transmission of open-loop control is difficult to achieve real-time linear adjustment, the working condition is single, and the error is large, which is far from the simulation of the actual parking operation state. Not enough, and the input adjustment is more troublesome

Embodiment Construction

[0021] see figure 1 , image 3 and Figure 4 , on the workbench, a pair of linear guide rods 10 are arranged in parallel, the guide plate 15 is set on the guide rods 10 on both sides through two linear bearings 14, and the drawing hook head 12 is fixedly arranged on the front side of the guide plate 15. This structure The form guarantees the directional stability of the pulling force in the stretching process; the back of the guide plate 15 is fixedly connected with the piston rod of the cylinder 4 through the S-shaped tension sensor 11; The detection probe of the pop-up position sensor 3 leans against the back of the guide plate 15; the compressed spring inside the sensor 3 ensures that the detection probe always keeps popping up within the range of the sensor 3, so that the detection probe can always lean against the guide plate 15. The back of the plate 15 moves synchronously to record the displacement of the wire drawing in real time.

Abstract

The invention discloses an automobile park lever force simulation device. The device is characterized in that a pair of linear guide rods are arranged in parallel on a work table, a guide plate is sheathed on the guide rods on two sides by two linear bearings, a wire drawing hook head is fixedly arranged on the front side of the guide plate, the guide plate is fixedly connected with a piston rod acylinder by a tension sensor on the back of the guide plate; a spring displacement transducer is arranged on a combined support of the work table, and a detection probe of the spring displacement transducer abuts against the back of the guide plate. The simulation device has the advantages of precision control, smooth movement, simple structure, convenient installation and maintenance, and can help effectively and really simulate automobile park lever force process.

Description

technical field [0001] The invention belongs to automobile bench test equipment, more specifically, it is a test device for simulating the parking tension in the detection test of the automobile braking system. Background technique [0002] The parking brake system is an important part of the car braking system. It can keep the car in place after stopping, can ensure that the car stops on a certain slope, and can also slow down the car in an emergency. The quality of its performance directly affects the safety performance of the car. At the same time, the operability of the parking device, that is, the drawing strength and the drawing stroke are also the main factors affecting the convenience of the driver. It is one of the important contents of the performance testing of the whole braking system to carry out relevant tests of the parking brake to test its safety and operability. [0003] At present, there is no special device for detecting the parking brake of passenger ca...
