Abstract
The utility model relates to an automobile part, in particular to a novel automobile reverse gear locking mechanism assembly which comprises a limiting bracket and a reverse gear locking plate which are connected movably through a spring and a pin. The novel automobile reverse gear locking mechanism assembly is characterized in that a dummy club is arranged on the contact surface between the limiting bracket and the reverse gear locking plate. The height of the dummy club is 0.3-1.5mm. The novel automobile reverse gear locking mechanism assembly has the advantages that the friction force between the limiting bracket and the reverse gear locking plate is reduced, the recovery capability of the spring is improved, and the problem that the transmission case can not be left in the reverse gear due to the jamming of the reverse gear locking mechanism assembly is thoroughly solved.
Description
Technical field
The utility model relates to a kind of automobile component, specifically a kind of new automobile reverse gear latching mechanism assembly.
Background technique
The reverse gear latching mechanism assembly is one of critical piece of automobile gearbox.It generally is formed by connecting by spring and bearing pin by the limiting bracket and the locking plate that reverses gear.Finding repeatedly in road test and user use that the part gearbox can not be hung reverses gear, and devans to check that finding reverses gear and between locking plate and the limiting bracket pollutant is arranged, and causes clamping stagnation, and the normally return of locking plate that reverses gear reverses gear thereby can not hang.From the product function of use, reverse gear locking plate and limiting bracket are that the requirement of relative movement part is rotated flexibly.Product analysis as shown in Figure 1, the gap that calculates reverse gear locking plate and limiting bracket from bearing pin, reverse gear locking plate and limiting bracket size and tolerance design is 0.1～0.75mm, in the actual production process, the gap of reverse gear locking plate and limiting bracket is 0.3～0.5mm, and the pollutant general thickness that causes clamping stagnation at present is 0.2～0.4mm.Enter in case pollutant takes place, following situation will take place: pollutant forms clamping stagnation at the B place, cause the locking plate that reverses gear to contact at the A point with limiting bracket.
Aligning torque=the Fc of clamping stagnation resistance torque=Fb * L1, spring * L2; Because L1＞8 * L2 clamping stagnation resisting moment much larger than the aligning torque of spring, causes the spring can't return and assembly clamping stagnation, causes gearbox not hang and reverses gear.Do not have effective way to overcome above-mentioned defective fully at present, be merely able to avoid dust and dirt to enter in the gearbox as far as possible, therefore invent a kind of reverse gear latching mechanism assembly and be highly profitable.
The model utility content
Technical problem to be solved in the utility model is exactly the defective that exists at existing automobile reverse gear latching mechanism, a kind of new automobile reverse gear latching mechanism assembly is provided, it has reduced the frictional force of reversing gear between locking plate and the limiting bracket, increase the return ability of spring, thoroughly solved reverse gear latching mechanism assembly clamping stagnation and caused gearbox can not hang the problem of reversing gear.
The technical solution of the utility model is achieved in that it comprises limiting bracket and the locking plate that reverses gear, and the limiting bracket and the locking plate that reverses gear flexibly connect by spring and bearing pin, it is characterized in that: be provided with boss on the surface of contact of the limiting bracket and the locking plate that reverses gear.Described boss height is 0.3-1.5mm, preferred 0.9mm; Reverse gear under this height locking plate and limiting bracket relative movement is the most flexible.
The utlity model has following advantage:
1, reduced area of contact between part, the corresponding frictional force that has reduced between part increases the return ability of spring relatively;
2, increased the relative gap of reverse gear locking plate and limiting bracket, conventional pollutant is got rid of easily.
3, under the situation that has pollutant to take place equally, change reverse gear locking plate and limiting bracket contact position, reduced the aligning torque of polluting clamping stagnation moment and increasing spring compared with before-improvement.
The utility model has reduced the frictional force of reversing gear between locking plate and the limiting bracket in sum, increases the return ability of spring, has thoroughly solved reverse gear latching mechanism assembly clamping stagnation and has caused gearbox can not hang the problem of reverse gear.

Fig. 2 is a structural representation of the present utility model
Fig. 3 is a stressed schematic representation of the present utility model
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 2, it comprises the limiting bracket 1 and the locking plate 2 that reverses gear the utility model, and the limiting bracket 1 and the locking plate 2 that reverses gear flexibly connect by spring 3, bearing pin 4, are provided with boss 5 on the surface of contact of the limiting bracket 1 and the locking plate 2 that reverses gear.Described boss 5 highly is 0.3mm, and reverse gear under this height locking plate and limiting bracket relative movement are the most flexible.
As shown in Figure 3, force-bearing situation of the present utility model is as follows during work:
Aligning torque=the Fc of clamping stagnation resistance torque=Fb * L1, spring * L2; Through experimental test L1＜2.5 * L2, the clamping stagnation resistance obviously reduces than L1 in the prior art＞8 * L2.
