Abstract
The utility model discloses a belt lock main reducer, reach the left side axle gear relative with driven bevel gear including driven bevel gear, right side axle gear, its characteristics are: the lateral surface of driven bevel gear is equipped with electromagnet actuator, is connected with the locking round pin that runs through driven bevel gear on electromagnet actuator's the driving piece, is equipped with the lockhole with the locking round pin adaptation on the left side gear side. The utility model discloses can pass through manual switch, control electromagnet actuator, make electromagnet actuator's driving piece drive the ejecting lockhole that gets into of locking pin, pin left side half axle gear and driven bevel gear, make differential mechanism lose the effect of differential, left side half axle gear does not have the speed difference with right side half axle gear promptly, left side half axle gear and right side half axle gear pass through the connecting axle and connect wheel hub and tire respectively, when vehicle one side tire is absorbed in the puddle, the adhesive force of this one side tire is not enough and produce idle running, but the opposite side tire can also rotate in step, rely on its adhesive force with ground to enable the vehicle to escape from the puddle and get rid of poverty.
Description
Technical Field
The utility model belongs to the technical field of auto parts, especially, relate to a main reducer with lock.
Background
The main speed reducer is used for transmitting torque and rotating speed from a transmission shaft to hubs on two sides through speed reduction and torque increase, and the requirements of speed change and direction change of vehicles such as advancing, retreating, turning and the like are met. It is usually composed of a drive bevel gear, a driven bevel gear, a side gear, a planetary gear, a gear carrier and the like.
The existing main reducer can meet the transmission requirements of turning, accelerating, decelerating, reversing and the like of a vehicle under normal road conditions, for example, one side of the vehicle is a mud pit when the vehicle runs to special road conditions, the adhesive force of a tire on one side suddenly becomes small and even disappears, but the existing main reducer distributes torque and rotating speed according to a normal proportion, so that a half shaft gear on the side with small adhesive force can continuously rotate, a hub tire connected with the main reducer can continuously idle, the half shaft gear on the side with large adhesive force can not rotate, the hub tire connected with the main reducer can not rotate, and the vehicle can not get trapped in the pit.
Disclosure of Invention
The utility model aims at providing a main reducer with lock to the not enough of above-mentioned prior art existence.
The utility model adopts the technical proposal that: the utility model provides a take lock main reducer, includes driven bevel gear, right side axle gear and the left side axle gear relative with driven bevel gear, driven bevel gear's lateral surface is equipped with electromagnet actuator, is connected with the locking round pin that runs through driven bevel gear on electromagnet actuator's the driving piece, is equipped with the lockhole with locking round pin adaptation on the left side axle gear side.
And the electromagnet driver is connected with a manual switch and a power supply through a lead.
After the structure is adopted, compared with the prior art, the utility model the advantage that has is: the utility model discloses can pass through manual switch, control electromagnet actuator, make electromagnet actuator's driving piece drive the ejecting lockhole that gets into of locking pin, pin left side half axle gear and driven bevel gear, make differential mechanism lose the effect of differential, left side half axle gear does not have the speed difference with right side half axle gear promptly, left side half axle gear and right side half axle gear pass through the connecting axle and connect wheel hub and tire respectively, when vehicle one side tire is absorbed in the puddle, the adhesive force of this one side tire is not enough and produce idle running, but the opposite side tire can also rotate in step, rely on its adhesive force with ground to enable the vehicle to escape from the puddle and get rid of poverty.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The following description is only for the preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereby, the present invention will be further explained with reference to the drawings and the embodiments.
Example, see figure 1: the utility model provides a take lock final drive, includes drive bevel gear 1, driven bevel gear 2 and differential mechanism, and differential mechanism comprises structures such as right side gear 3, left side gear 4 relative with driven bevel gear 2, carrier, and its detailed structure and connected mode are the same with prior art, and it is no longer repeated here. An electromagnet driver 5 is arranged on the outer side surface of the driven bevel gear 2, a driving piece of the electromagnet driver 5 is connected with a locking pin 6 penetrating through the driven bevel gear 2, and a locking hole matched with the locking pin 6 is formed in the side surface of the left half axle gear 4; the electromagnet driver 5 is connected with a manual switch and a power supply through a lead. The electromagnet driver 5 is controlled through a manual switch, so that a driving piece of the electromagnet driver 5 drives a locking pin 6 to be ejected out of a locking hole, the left half axle gear 4 and the driven bevel gear 2 are locked, the differential loses the differential action, namely the left half axle gear 4 and the right half axle gear 3 have no speed difference, the left half axle gear 4 and the right half axle gear 3 are respectively connected with a hub and a tire through a connecting shaft, when the tire on one side of a vehicle sinks into a mud pit, the tire on the side is not enough in adhesive force to generate idle rotation, but the tire on the other side can also synchronously rotate, and the vehicle can escape from the mud pit and get out of the ground by virtue of the adhesive force between the tire and the ground.
Claims (2)
1. The utility model provides a take lock final drive, includes driven bevel gear, right side axle gear and the left side axle gear relative with driven bevel gear, its characterized in that: the lateral surface of driven bevel gear is equipped with electromagnet actuator, is connected with the locking round pin that runs through driven bevel gear on electromagnet actuator's the driving piece, is equipped with the lockhole with the locking round pin adaptation on the left side gear side.
