Abstract

The invention discloses an automatic energy recovering device for a driving axle of a heavy-duty truck. The automatic energy recovering device comprises a generator arranged on a frame, and a transmission device for transmitting a rotating speed in a wheel braking process to the generator, wherein the transmission device comprises a driving gear which is in separable normal-running fit with a wheel axle, and a driven gear which is in meshed transmission with the driving gear and is used for driving a rotor and a stator of the generator to move relatively to each other. The automatic energy recovering device can be used for recovering energy according to a braking process and assisting in braking, is suitable to be installed and used in an automobile, and is used for recovering energy, assisting in braking simultaneously and reducing and avoiding bearing high braking load, so that requirements are lowered, the service life is prolonged, and the manufacturing cost and using cost are lowered; the recovering device has a simple layout, and contributes to axle shell design, and the overall strength and rigidity of the axle are not influenced; and the recovering device has the characteristics of high reliability, long service life, low energy consumption, small size and light weight, and the production and manufacturing costs are low, and convenience is brought to installation, detachment and maintenance.

Description

Technical field [0001] The invention relates to a braking energy recovery device, in particular to an automatic energy recovery device for a heavy-duty vehicle drive axle. Background technique [0002] Braking energy has been widely studied as the main dissipated energy during the driving process of automobiles. With the advent of the energy crisis, major automobile manufacturers have begun to study the recovery system of automobile brake energy. In the prior art, the brake energy recovery device has a low transmission ratio, and has poor adaptability to braking energy recovery under low-speed operating conditions, and has great limitations. Generally, it can only complete energy recovery under high-speed operating conditions. For various working conditions of automobile driving, the current development of brake energy recovery system still has limitations. [0003] In particular, heavy-duty vehicles have greater inertia during driving, so the required braking force is greater, th...
