Abstract
A drum brake mounting structure of an electric car comprises a drum brake assembly installed on a rear axle and tightly pressed against a hub and a rear fork, and the drum brake assembly comprises a drum brake cover. The drum brake mounting structure is characterized in that one end of the drum brake cover is provided with a U-shaped limiting groove, a drum brake positioning pillar is fixed to the rear for, and the drum brake positioning pillar corresponds to the limiting groove. The U-shaped limiting groove in the drum brake cover cooperates with the drum brake positioning pillar on the rear fork, which restricts rotation of the drum brake. An intermediate transition member and a movable part are not needed, and the drum brake is installed on a vehicle body more stable and reliable. The drum brake mounting structure facilitates installation.
Description
Technical field
The utility model relates to a kind of battery-driven car annex, specifically a kind of electric motor vehicle drum brake mounting structure.
Background technology
The brake of battery-driven car is the key that guarantees safety, and drum is stopped because simple in structure, good reliability, cost are low, is widely used on battery-driven car.Drum is stopped needs a positioning groove to prevent from rousing the disc spins of stopping while being arranged on battery-driven car, in prior art, generally adopt a banking stop, one end is connected on the rear chain stay of battery-driven car, the other end is connected to rouse stops dish above, and the benefit of this structure is to adjust the distance that drum is stopped dish and rear bottom fork of electric vehicle.The existing drum mounting structure of stopping exists following shortcoming: banking stop adopts screw to connect, and in long-term driving process, produces vibration and can make banking stop displacement, even can come off, thereby affect braking effect when serious.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of improved mounting structure of electric motor vehicle drum brake, and it is simple in structure, easy for installation, and make drum stop on car body, install reliable and stable.
For reaching above-mentioned purpose, the utility model is by the following technical solutions: a kind of mounting structure of electric motor vehicle drum brake, comprise bulging brake assembly and rear chain stay, drum brake assembly is arranged on hind axle, and be close to wheel hub, drum brake assembly comprises the drum lid of stopping, and it is characterized in that: there is the position-limited trough of U-shaped stop one end of covering of described drum, on described rear chain stay, be fixed with the bulging registration mast of stopping, the bulging registration mast position of stopping is corresponding with position-limited trough.
The beneficial effects of the utility model: the utility model matches by drum position-limited trough and the drum on rear chain stay of the U-shaped that the covers registration mast of stopping of stopping, limited the rotation that drum is stopped, and there is no middle transition part and mobilizable parts, drum stop be arranged on car body more reliable and more stable, simultaneously owing to having reduced the installation of banking stop, simple in structure, easy for installation.
Accompanying drawing explanation
Fig. 1 is the front view of an embodiment of the utility model.
Fig. 2 is the birds-eye view of an embodiment of the utility model.
In figure, 1. hind axle, 2. rear chain stay, the 3. drum lid of stopping, 31. position-limited troughs, the 4. bulging registration mast of stopping.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further detailed:
A kind of mounting structure of electric motor vehicle drum brake, comprise bulging brake assembly and rear chain stay 2, drum brake assembly is arranged on hind axle 1, and be close to wheel hub, drum brake assembly comprises that drum stops and cover 3, it is characterized in that: described drum is stopped and covered the position-limited trough 31 that there is U-shaped one end of 3, be fixed with the drum registration mast 4 of stopping on described rear chain stay 2, drum registration mast 4 positions of stopping are corresponding with position-limited trough 31.Described position-limited trough 31 openings are to external expansion.
