AI Technical Summary

Problems solved by technology

However, it still cannot completely solve the problem of air bubbles in the oil circulation. Once the air bubbles occur in the oil, the circulation of the oil will be reduced, which will affect the work of the shock absorber. At this time, only the spring acts as a shock absorber. Function, when the vehicle encounters big bumps or rolls, the vehicle will bounce non-stop, just like a bouncy ball, no passenger can stand it, and the stability and ride comfort cannot be guaranteed

Embodiment Construction

[0013] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0014] Such as Figure 1-Figure 2 As shown, a connecting rod includes a piston rod body 1, and the overall length R1 of the piston rod is 405mm. In addition, a chrome-plated layer is provided on the outer surface of the piston rod body 1 .

[0015] A piston core rod 2 and a connecting screw 3 are provided at the front end of the piston rod body 1; a first step 4 with a first chamfer and a fourth step are provided between the piston core rod 2 and the piston rod body 1 Step 5. The first step 4 is in the shape of a truncated cone, and the thickness L2 of the first step 4 is 3cm-4cm; in the present invention, the thickness L2 of the first step 4 is 3.9cm.

[0016] The taper θ2 of the first step 4 is 20°; the piston core rod 2 and the first step 4 are connected by a fourth step 5 with a second chamfer; the taper of the fourth step 5 θ1 is 45°; the fourth step...

Abstract

The invention discloses a connecting rod, which comprises a connecting rod body, a piston core rod and a connecting screw rod are arranged at the front end of the connecting rod body; a first chamfer is arranged between the piston core rod and the connecting rod body The first step; the first step is in the shape of a truncated cone, and the taper of the first step is 20°; the thickness of the first step is 3cm-4cm; between the piston core rod and the first The steps are connected by a fourth step with a second chamfer; the taper of the fourth step is 45°. The invention improves the fluidity of the oil and prevents the air bubbles generated when the oil flows from affecting the normal operation of the shock absorber.

Description

technical field [0001] The invention relates to an automobile accessory, in particular to a connecting rod used on a shock absorber. Background technique [0002] In the suspension system, the elastic elements vibrate due to the impact. In order to improve the ride comfort of the car, shock absorbers are installed in parallel with the elastic elements in the suspension. The working principle of the shock absorber is that when the frame (or body) and the axle are vibrated and there is relative movement, the piston in the shock absorber moves up and down, and the oil in the shock absorber chamber repeatedly passes through different chambers. The pores flow into another cavity. At this time, the friction between the hole wall and the oil and the internal friction between the oil molecules form a damping force on the vibration, so that the vehicle vibration energy is converted into oil heat energy, which is then absorbed by the shock absorber and released into the atmosphere. ...
