Abstract

The utility model provides a vehicle head turnover torsion bar, and is characterized in that the utility model consists of a left torsion bar and a right torsion bar. The left torsion bar and the right torsion bar are an L-shape. The lower ends of the left torsion bar and the right torsion bar are clamped on the corresponding position of a vehicle frame, the middle parts of the torsion bars are inserted into the corresponding limitation points, and then the upper end points of the torsion bars are inserted into upper end clamping points and fixed by a cotter pin. The vehicle head turnover torsion bar has the advantages of the simple structure, low cost, good universal performances of the components, reliable use, less processes, simple operation and processing, easy assembly, etc.

Description

Headstock upset torsion bar

Technical field

The utility model belongs to the Manufacturing Technology for Automotive Parts field, particularly a kind of headstock upset torsion bar.

Background technology

Present domestic bonneted truck headstock upset servomechanism generally adopts six connecting rods upset stop gear or the straight torsion bar in wounded in the battle key termination, above-mentioned six connecting rods upset stop gear more complicated, adopt the straight torsion bar upset of spline end power-assisted then processing, the processing of torsion bar itself to be had the higher requirement of ratio, therefore, need producer to possess very high professional manufacture level, these all can cause the torsion bar cost to increase.

Summary of the invention

The purpose of this utility model is exactly the deficiency at said structure, and a kind of headstock upset torsion bar is provided.

The technical solution of the utility model is achieved in that

Headstock upset torsion bar, it is characterized in that: it is made up of left torsion bar, right torsion bar, left side torsion bar and right torsion bar are the approximate shape of L, earlier left torsion bar, right torsion bar lower end are stuck in corresponding position on the vehicle frame, and the torsion bar middle part is inserted into corresponding limit site, then the torsion bar upper extreme point is inserted stuck point place, upper end, fix with spring cotter.

The utlity model has simple in structurely, cost is low, and component universality is good, uses reliably, and operation is few, and process operation is easy, assembles characteristics such as easy.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Specific embodiments

Further describe the technical solution of the utility model below in conjunction with accompanying drawing and instantiation.

As shown in Figure 1, when the left torsion bar 2 of headstock upset torsion bar and right torsion bar 7 are made, the spring wire that satisfies specification requirement is cut off, carrying out cold bend(ing) then handles and can be shaped, left side torsion bar 2 and right torsion bar 7 are made the approximate shape of L, earlier with left torsion bar 2, right torsion bar 7 lower ends are stuck in corresponding position on the vehicle frame, and the torsion bar middle part is inserted into corresponding limit site, then the torsion bar upper extreme point is inserted upper end stuck point 1 and stuck point 6 places, fix with spring cotter, middle part on a left side torsion bar 2 and the right torsion bar 7 has spacing 3 and spacing 8, and the bottom has spacing 4 and spacing 9, in the overturn junction of torsion bar of vehicle frame and headstock stuck point 5 and stuck point 10 is arranged.

Claims
