Description

Electric motor car rear drum cover

Technical field

This utility model relates to a kind of rear drum cover, more specifically, it relates to a kind of electric motor car rear drum cover.

Background technology

Electric motor car rear drum cover is again rear drum brake of electric vehicle, is the one of brake of electric vehicle device, and the existence of stopping of traditional rear drum is stopped in lid easily hydrops, the shortcoming of easy-to-rust.

At present, application number be 201120141142.1 Chinese patent disclose a kind of rear drum brake of electric vehicle, mainly include lid of stopping, drum is installed in described lid of stopping stop assembly and drive the flat slide block rousing assembly of stopping, described lid outside of stopping is provided with to rotate the rocking arm of slide block, described lid inwall of stopping offers a circle capillary groove, it is positioned on the lid outer ring of stopping outside capillary groove and offers scupper, hydrops can be discharged by capillary groove and scupper, solve to prevent from stopping the problem of lid internal water accumulation, although such scheme can play the effect of the lid internal water accumulation that prevents from stopping, but its waterproof effect is limited, it is known that, wheel hub can produce axial pull strength in the process of high speed rotating, having little time the hydrops from scupper outflow in capillary groove can towards axial flowing, cause soaking of brake assemblies, cause that braking effect weakens.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is in that to provide the electric motor car rear drum cover of a kind of good water-proof effect.

For achieving the above object, this utility model provides following technical scheme: a kind of electric motor car rear drum cover, including drum lid body, drum is installed inside described bulging lid body stop assembly and for driving drum to stop the slide block of assembly, described bulging lid outer body is provided with to rotate the rocking arm of slide block, offer a circle capillary groove inside described bulging lid body, be positioned on the cell wall outside capillary groove and offer scupper, be positioned on the cell wall inside capillary groove to offer a circle and block water groove.

By above-mentioned setting, electric motor car is in the process travelled, it is seeped into the water in electric motor vehicle drum lid can amass in capillary groove, and flow out from the scupper of capillary groove lateral wall, the hydrops having little time to flow out due to a part can along axial flowing in the process of wheel hub high-speed rotation, the groove that blocks water just is located on capillary groove inwall, receive the hydrops flow through, effective stop hydrops continues to flow to the inside, add one barrier more, being blocked in the hydrops blocking water in groove flowing back to capillary groove and flowing out from scupper, waterproof effect is better.

Preferably, it is positioned at the cell wall of scupper both sides to stretch out and form the tongue that leaks of bottom lock.

By above-mentioned setting, in the process that electric motor car travels, the water and the silt that effectively prevent ground enter from scupper towards the opening on ground, the tongue that leaks protrudes from the cell wall outside capillary groove, its hydrops flow export is positioned at the side of projection, not only can guarantee that the hydrops in electric motor car rear drum cover flows out from the side of the tongue that leaks but also can effectively prevent the water in the external world and silt from entering from bottom.

Preferably, the outside of described bulging lid body is provided with lug, and described lug offers the through hole for fixing brake cable.

By above-mentioned setting, the through hole that brake cable can be previously threaded through on lug pre-fixes, and without utilizing extra part, the lug fixed effect of a system is more stable simultaneously.

Compared with prior art, the beneficial effects of the utility model are: the groove that blocks water has received the hydrops flowed axially through, and effective stop hydrops continues to flow to the inside, adds one barrier more, being blocked in the hydrops blocking water in groove flowing back to capillary groove and flowing out from scupper, waterproof effect is better.

Detailed description of the invention

For making the purpose of this utility model, technical scheme and advantage clearly, this utility model is done describe clearly and completely further below with reference to accompanying drawings. Obviously, described embodiment is section Example of the present utility model, rather than whole embodiments. Based on described this utility model, the every other embodiment that those of ordinary skill in the art obtain under the premise without creative work, broadly fall into the scope of this utility model protection.

Electric motor car rear drum cover as shown in Figure 1, including drum lid body 1, drum is installed inside described bulging lid body 1 stop assembly 2 and for driving drum to stop the slide block 3 of assembly 2, described brake assemblies includes hoof block group 11, centering spindle 12, extension spring 13, hoof block group 11 is the hoof block of two semicirculars in shape, the outer surface of hoof block is provided with friction plate, one end of two hoof blocks is fixed by centering spindle 12, slide block 3 is held on and is formed with a circle by the other end respectively, the two ends of two hoof blocks are strained each through extension spring 13, described slide block 3 is in flat, rotate the slide block 3 of flat, two hoof blocks can be strutted by slide block 3, hoof block is made to laterally rotate respectively around centering spindle 12, in order to reduce the abrasion when slide block 3 contacts of the hoof block, the one end contacted with slide block 3 at two hoof blocks is equipped with abrasionproof contact pin, it is provided with to rotate the Rocker arm 4 of slide block 3 outside described bulging lid body 1, Rocker arm 4 is provided with torsion spring, the other end of torsion spring is fixed on bulging lid body 1, rotate Rocker arm 4, Rocker arm 4 can drive slide block 3 to rotate, unclamp Rocker arm 4, torsion spring can make Rocker arm 4 set back, such as Fig. 2, shown in 3, a circle capillary groove 5 is offered inside described bulging lid body 1, it is positioned on the cell wall outside capillary groove 5 and offers scupper 6, it is positioned on the cell wall inside capillary groove 5 to offer a circle to block water groove 7, the groove 7 that blocks water is equivalent on the inwall of capillary groove 5 ring cutting one circle groove, the upper surface of groove 7 of blocking water is all concordant with the inwall of capillary groove 5, its part concaved is for receiving hydrops, electric motor car is in the process travelled, it is seeped into the water in electric motor vehicle drum lid and can amass in capillary groove 5, and flow out from the scupper 6 of capillary groove 5 lateral wall, the hydrops having little time to flow out due to a part can along axial flowing in the process of wheel hub high-speed rotation, the groove 7 that blocks water just is located on capillary groove 5 inwall, receive the hydrops flow through, effective stop hydrops continues to flow to the inside, add one barrier more, it is blocked in the hydrops blocked water in groove 7 flowing back to capillary groove 5 and flowing out from scupper 6, waterproof effect is better.
