Problems solved by technology

[0004] Most of the existing wheel hub motor layout schemes are equipped with single tires, which are not suitable for the hub motor layout of dual tire drive vehicles. In addition, the existing hub electrical integration schemes are equipped with disc system The braking force of disc brakes is not large enough to be suitable for heavy-duty vehicles, and the cost of disc brakes is high and friction linings need to be replaced frequently

Abstract

The invention provides a hub motor integrated system which is arranged in a dual wheel. The system comprises a hub motor, a speed reducer and a brake. The brake is a drum brake and comprises a brake drum connecting piece, a brake shoe, brake wheel cylinders, a brake drum and a brake bottom board. The specially-manufactured drum brake is adopted for substituting an existing disc brake of a heavy load vehicle, brake force is large, the drum brake is more suitable for braking a rear wheel of the heavy load vehicle, and the application range of the hub motor technology is enlarged; and for the heavy load vehicle, the vehicle traveling speed is low, the required brake force is large, under the condition, the durability of the drum brake is higher than that of the disc brake, the brake stabilityof the heavy load vehicle can be improved, and cost is saved as well.

Description

technical field [0001] The invention belongs to the field of new energy vehicles, and in particular relates to an integrated system of hub motors. Background technique [0002] With the depletion of global energy and the gradual deterioration of the global environment, the development of new energy vehicles has become the consensus of automobile companies. New energy vehicles will undoubtedly improve the pollution of the global environment, and at the same time help the use of clean energy, reduce the development of oil resources, and ensure Sustainability of Earth's resource use. New energy vehicles have special significance to our country. Most of our country's oil resources rely on imports, which is extremely detrimental to our country's energy security. In addition, our country's environmental pollution problem is becoming more and more serious. Solving the problem of environmental pollution is related to the national economy and people's livelihood. In addition, my coun...
