Abstract
The utility model provides a combined piston structure of a main cylinder of a clutch. The combined piston structure comprises a main piston, a secondary piston and a piston push rod, wherein the main piston and the secondary piston are connected together through a universal joint; one end of the secondary piston is matched with the main piston; and the other end of the secondary piston is fixedly connected with the piston push rod. According to the combined piston structure of the main cylinder of the clutch, a piston split combined structure is adopted, and the main piston and the secondary piston are adopted and are connected through the universal joint, so that the phenomenon that the piston wears a cylinder body when a pedal wears in a deflection way can be reduced, and the wearproof performance is improved. Meanwhile, the main piston is made of an aluminum material, so that the structure is easy to machine and mold, the structure is relatively high in compression strength; and the secondary piston is made of plastic, so that the cost is low.
Description
Technical field
The utility model belongs to the clutch master cylinder component, is specifically related to a kind of clutch master cylinder Combined piston structure.
Background technique
Clutch is installed between motor and the speed changer, is total member direct in the automotive transmission and that motor interrelates.Usually clutch is installed together with engine crankshaft flywheel group, is the parts of cut-out and transferring power between motor and the automotive transmission.Clutch master cylinder is the vitals of clutch, is provided with piston in clutch master cylinder.Present piston of the prior art all is the integral type structure, mainly adopts aluminum material to make.But this piston easily weares and teares poor durability when the pedal eccentric wear.
The model utility content
The utility model provides a kind of clutch master cylinder Combined piston structure of good endurance for above-mentioned the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
A kind of clutch master cylinder Combined piston structure, it is characterized in that, comprise main piston, sub-piston and piston push rod, described main piston and sub-piston link together by universal joint, one end of described sub-piston cooperates with main piston, and the other end is fixedly connected with piston push rod.
Further setting of the present utility model is, the middle part of described main piston is provided with for the groove to relief chamber repairing feed flow.
Further setting of the present utility model is, the material of described main piston and sub-piston is different.
Further setting of the present utility model is, described main piston is an aluminum piston, and described sub-piston is a plastic piston.
Further setting of the present utility model is, is set with the main piston leather cup on the described main piston, is set with the sub-piston leather cup on the sub-piston.
Clutch master cylinder Combined piston structure described in the utility model adopts the structure of piston separate assembling, and minute major and minor double-piston, two-piston adopt universal joint to connect, and can reduce the piston wear cylinder body that the pedal eccentric wear is introduced, and improve endurance quality.Main piston adopts aluminum material simultaneously, easily shapes, and stronger compressive strength is arranged; Sub-piston adopts plastic construction, and is with low cost.
Description of drawings
Fig. 1 is the structural drawing of clutch master cylinder Combined piston structure described in the utility model.
Embodiment
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the utility model provides a kind of clutch master cylinder Combined piston structure, comprise main piston 1, sub-piston 2 and piston push rod 3, described main piston 1 and sub-piston 2 link together by universal joint, one end of described sub-piston 2 cooperates with main piston 1, and the other end is fixedly connected with piston push rod 3.The middle part of described main piston 1 is provided with groove, is used for to relief chamber repairing feed flow.For better sealing, be set with main piston leather cup 4 on the described main piston 1, be set with sub-piston leather cup 5 on the sub-piston 2.
Main piston described in the utility model 1 is different with the material of sub-piston 2, and described main piston 1 is an aluminum piston, and it easily shapes, and stronger compressive strength is arranged; Described sub-piston 2 is a plastic piston, and cost is lower.
The above is preferred embodiment of the present utility model, and all equivalent variations of doing according to the utility model claim all should belong to protection domain of the present utility model.
