Abstract

An energy-accumulating brake for car is composed of energy-accumulating spring, planetary gear mechanism, oil cylinder communicated with brake cylinder, and electromagnetic unit. When the automobile is braked, the planet gear carrier is also braked by the piston in the oil cylinder, the gear ring enables the sun gear to run at an overspeed in the same direction through the planet gear, and the energy storage spring is wound up for energy storage. When the automobile is stopped after braking, the central gear can not rotate under the action of the roller, so that the spring is in an energy storage state. When the automobile starts to run, the spring with full energy can only apply force to the spring box when the sun gear can not rotate due to the release of all brakes including the planet gear carrier, and the spring box and the power generated by the automobile engine drive the driving shaft to run to enable the automobile to move forwards until the spring energy is completely released. The energy can not be stored when the automobile is braked in a backing way.

Description

Automobile brake energy storage device

Technical Field

The utility model relates to an automobile energy recycling device, in particular to a braking energy storage device installed on an automobile driving shaft.

Background

When the existing automobile brakes, the kinetic energy of the automobile is converted into heat energy through the friction between a brake shoe and a brake drum (or disc) and the heat energy is dissipated into the air, so that the energy waste is caused.

Disclosure of Invention

In order to avoid the whole waste of energy when the car brakes, the utility model provides a car braking energy storage equipment, it can partially hold the kinetic energy of car when the braking, then releases the car again and goes in.

The utility model provides a technical scheme that its technical problem adopted is: the spring box is fixed on the rear driving shaft of the automobile gearbox and rotates along with the driving shaft. One end of the spring is fixed on the spring box, and the other end is fixed on the central gear. The central gear is movably sleeved on the reverse gear rotating disc, and a roller is arranged between the central gear and the reverse gear rotating disc, so that the central gear can only rotate in one direction relative to the reverse gear rotating disc. The reverse gear rotating disc is sleeved on the shaft sleeve and limited by the clamp spring, and the reverse gear rotating disc can only rotate on the shaft sleeve and cannot axially move. The shaft sleeve is fixed on a machine body (such as a gearbox body). The gear ring is fixedly arranged on the spring barrel and rotates along with the spring barrel, and the planet wheel is double-wheel, so that the gear ring and the central gear are ensured to rotate in the same direction. The planet wheel is supported by a left planet wheel carrier and a right planet wheel carrier which are riveted into a whole through a planet wheel shaft, the left planet wheel carrier and the spring barrel form a complete spring barrel, and a brake drum is arranged on the right planet wheel carrier. The base is fixed on the shaft sleeve, and an oil cylinder and an electromagnetic device are arranged on the base. The oil cylinder is communicated with the automobile brake cylinder, and a piston in the oil cylinder directly acts on a brake drum on the right planetary gear carrier. When the automobile is not in reverse gear, the electromagnetic coil in the electromagnetic device is not electrified, and the movable iron core presses the reverse gear rotating disc under the action of the spring, so that the reverse gear rotating disc is not rotated.

When the running automobile is braked, the cylinder communicated with the brake cylinder simultaneously enters brake fluid to push the plunger to press the brake drum on the right planet gear carrier, the planet gear carrier is braked, at the moment, the automobile only reduces the speed of the automobile and still moves forward, because the planet gear carrier is braked, the gear ring makes the sun gear overspeed in the same direction through the planet gear, and the spring connected with the sun gear is wound up to store energy. If the central gear winds up the spring completely and tightly, no relative running space exists between the central gear and the gear ring, and the automobile is not stopped in continuous braking, the central gear can synchronously rotate along with the spring box and the gear ring only under the action of the wound spring, the friction force between the plunger and the brake drum of the right planet gear carrier is forcibly overcome, and the planet gear carrier and the planet gears integrally and synchronously rotate until the automobile is stopped.

When the automobile is parked, the spring is in the energy storage state. The foot brake is not released, the driving shaft, the spring barrel, the gear ring and the planet gear carrier are all in the brake state, the gear teeth of the planet gear mechanism are meshed with each other, and the central gear cannot rotate. When the hand brake is tightened by loosening the foot brake, the brake of the planetary gear carrier is released although the driving shaft, the spring barrel and the gear ring are braked, the planetary gear carrier, the planetary gear and the sun gear can freely move mutually, the sun gear rotates under the action of the spring, and at the moment, the roller can not rotate the sun gear, so that the energy accumulated by the spring is not released when the vehicle is stopped.

When the automobile is started after the braking is released, the central gear cannot rotate because the spring barrel is not braked, and the spring full of energy can only apply force to the spring barrel and drive the driving shaft to run together with the driving force of the automobile engine so as to enable the automobile to advance until the energy of the spring is completely released. After the energy of the spring is completely released, the spring does not apply force to the central gear, the roller is in a free state, the running spring box drives the central gear to cross the roller through the spring, the spring box runs around the reverse gear rotating disc, the planetary gear mechanism also integrally and synchronously rotates along with the spring box, and the automobile enters normal running.

When the automobile is reversed backwards, a reverse gear is hung, the reverse gear circuit is switched on, the electromagnetic coil on the base is electrified, the movable iron core is sucked up, and the reverse gear rotating disc is in a free rotating state. When backing, the driving shaft of the automobile reversely rotates to drive the spring box, the spring, the central gear and the roller are pulled to make the freely rotating reverse gear rotating disc rotate on the shaft sleeve together, and the planetary gear mechanism also integrally rotates (note that energy can not be stored when backing).

The beneficial effects of the utility model are that, partial energy when it can absorb the car braking, then release the car again and go in, it is extravagant to reduce the energy, especially is suitable for and crosses traffic lights such as intersection with the car, need not to increase the throttle when green light is let pass and makes the automobile start, reduces city air pollution.

Detailed Description

In fig. 1, a barrel 2 is fixed to a drive shaft 1 and rotates with the drive shaft 1. Spring 4 is fixed at one end to barrel 2 and at one end to sun gear 16 (see fig. 1, 3). The sun gear 16 is movably sleeved on the reverse gear rotating disc 15, and a roller 17 is arranged between the sun gear 16 and the reverse gear rotating disc 15, so that the sun gear 16 can only rotate in one direction relative to the reverse gear rotating disc 15 (see fig. 1 and 2). The reverse gear rotating disc 15 is sleeved on the shaft sleeve 18 and limited by the clamp spring 19, and the reverse gear rotating disc 15 can only rotate on the shaft sleeve 18 and cannot move axially. The shaft sleeve 18 is fixed to a body (e.g., a transmission housing). The toothed ring 7 is fixedly arranged on the spring barrel 2 and rotates along with the spring barrel 2, and the planet wheel 6 is a double wheel (see figure 2), so that the rotating directions of the toothed ring 7 and the central gear 16 are consistent. The planet wheel 6 is supported by a left planet wheel carrier 3 and a right planet wheel carrier 10 which are riveted into a whole through a planet wheel shaft 5, the left planet wheel carrier 3 and the spring barrel 2 form a complete spring barrel, and a brake drum is arranged on the right planet wheel carrier 10. The base 13 is fixed on the shaft sleeve 18, and the oil cylinder 8 and the electromagnetic device are arranged on the base 13. The oil cylinder 8 is communicated with an automobile brake cylinder, and a piston 9 in the oil cylinder 8 directly acts on a brake drum on the right planet gear carrier 10. When the automobile is not in reverse gear, the electromagnetic coil 11 in the electromagnetic device is not electrified, and the movable iron core 14 is pressed to the reverse gear rotating disc 15 under the action of the spring 12, so that the reverse gear rotating disc 15 is fixed on the base 13 and does not rotate.

When the running automobile is braked, the cylinder 8 communicated with the brake cylinder simultaneously enters brake fluid, the plunger 9 is pushed to press a brake drum on the right planet carrier 10, the planet carriers 3 and 10 are braked (see figure 1), the automobile still moves forwards only when the speed of the automobile is reduced, the ring gear 7 enables the sun gear 16 to run over speed in the same direction (n direction) through the planet gears 6 due to the fact that the planet carriers 3 and 10 are braked, and the spring 4 connected to the sun gear 16 is wound up to store energy (see figure 2 and figure 3). If the sun gear 16 winds the spring 4 completely, no relative running space exists between the sun gear 16 and the ring gear 7, and the automobile is not stopped in continuous braking, at this time, the sun gear 16 can synchronously rotate along with the spring barrel 2 and the ring gear 7 only under the action of winding the spring 4, the friction force between the plunger 9 and the brake drum of the right planet carrier 10 is forcibly overcome, and the planet carriers 3 and 10 and the planet wheel 6 integrally and synchronously rotate together until the automobile is stopped (meanwhile, the braking force of the automobile is also increased).

When the automobile is parked, the spring 4 is in the energy storage state. The foot brake is not released, the driving shaft 1, the spring barrel 2, the gear ring 7, the left planet gear carrier 3 and the right planet gear carrier 10 are all in the braking process, the gear teeth of the planet gear mechanism are meshed with each other, and the sun gear 16 cannot rotate. When the hand brake is tightened by releasing the foot brake, the driving shaft 1, the spring barrel 2 and the gear ring 7 are braked, but the left planetary gear carrier 3 and the right planetary gear carrier 10 are braked and released, the planetary gear 6, the planetary gear carriers 3 and 10 and the sun gear 16 can move freely mutually, the sun gear 16 rotates under the action of the spring 4, and the roller 17 prevents the sun gear 16 from rotating (see figure 2), so that the energy accumulated by the spring 4 is not released when the vehicle is stopped.

When the automobile is braked and started to run, the driving shaft 1, the spring barrel 2, the gear ring 7, the left planetary gear carrier 3 and the right planetary gear carrier 10 are braked and released (see figure 1), the sun gear 16 cannot rotate under the action of the roller 17 (see figure 2), the spring 4 with full energy can only apply force to the spring barrel 2, and the driving shaft 1 is driven to run in the n direction (see figure 2) together with the driving force of the automobile engine to enable the automobile to advance until the energy of the spring 4 is completely released. After the energy of the spring 4 is completely released, the spring 4 does not apply force to the central gear 16, the roller 17 is in a free state, the spring barrel 2 running in the n direction drives the central gear 16 to cross the roller 17 to run around the reverse gear rotating disc 15 (see figure 2) through the spring 4, the planetary gear mechanism also integrally and synchronously rotates along with the central gear 16, and the automobile enters normal running.

When the automobile is reversed backwards, a reverse gear is engaged, the reverse gear circuit is switched on, the electromagnetic coil 11 on the base 13 is electrified, the movable iron core 14 is sucked up, and the reverse gear rotating disc 15 is in a free rotating state (see fig. 1). When the automobile is reversed, the automobile driving shaft rotates backwards in the reverse direction n to drive the spring box 2, the spring 4, the central gear 16 and the roller 17 are pulled, the freely rotating reverse gear rotating disc 16 rotates on the shaft sleeve 18 together, and the planetary gear mechanism also rotates along with the spring box (note that energy cannot be stored when the automobile is reversed).
