Abstract
The utility model provides a driven wheel of an automobile main reducer and belongs to the technical field of automobile parts. The driven wheel of the automobile main reducer solves the problem that the side wall of a groove on the end face of a driven wheel body of an existing main reducer is perpendicular to the bottom wall of the groove, assembly of universal joints can be influenced by the edge formed by the groove and the end face often, and simultaneously the structure is not compact. The driven wheel of the automobile main reducer comprises a gear body, gear teeth are arranged on the outer circumference of the gear body, annular grooves are arranged on two end faces of the gear body, the bottom walls of the annular grooves are parallel to the end face of the gear body, and the peripheral walls of the annular grooves are inclined relative to the bottom walls. During assembly, the peripheral walls of the annular grooves are inclined relative to the bottom walls, space occupied by the annular grooves is increased, and assembly of parts such as the universal joints located on one side of the driven wheel is facilitated. Simultaneously, the thickness of the bottom ends of the annular grooves is reduced relative to the thickness of the peripheral wall of the body, and the original strength of the gear is guaranteed.
Description
Technical field
The utility model belongs to technical field of automobile parts, particularly a kind of follower of automobile main reducer.
Background technique
Automotive transmission is the speed change gear that a cover is used for the actual travel speed of coordination engine speed and wheel, can bring into play like this optimum performance of motor.In vehicle traveling process, speed changer passes to live axle to the power of motor with suitable moment of torsion and rotating speed by the transforming gear of gear transmission and speed changing structure, to adapt to automobile requirement to tractive force and travelling speed under different road conditions.
Generally comprise input shaft, output shaft, jack shaft on the speed changer, be set in gear and synchronizer on input shaft, jack shaft and the output shaft.The shaft axis of input shaft and output shaft is on same straight line but be not connected to each other the shaft axis of jack shaft and the axis parallel of input shaft.Be arranged with the driven gear of each gear at input shaft; Movable sheath is provided with the driving gear of each gear on output shaft; Synchronizer is installed on the output shaft and between driving gear, synchronizer under the effect of shift fork can with adjacent gear in conjunction with tooth in conjunction with or separate.The clutch connecting engine is passed in the one end connection of input shaft, be set in the engagement of gear on the input shaft and the gear on the jack shaft and with the power transmission of motor to jack shaft, the driving gear that is movably set on the output shaft given transmission of power by gear on the jack shaft, driving gear is given transmission of power on the synchronizer that fixes with output shaft, synchronizer drives output shaft rotation, then output shaft with transmission of power to live axle.So just finished power by the whole process of starting to pass to output shaft.
Main reducing gear is the deceleration that reduces the gear that speed changer passes in the automotive transmission, the critical piece that increases moment of torsion between speed changer and live axle.Automobile is when normally travelling, the rotating speed of motor is usually about 2000 to 3000r/min, if so high rotating speed is only reduced by gearbox, the velocity ratio of gearbox internal gear then needs very large so, and the velocity ratio of gear is larger, the radius ratio of two gears is also larger, in other words, namely the size of gearbox can design larger; Simultaneously, rotating speed descends, and moment of torsion must increase, and has also just strengthened behind gearbox and the gearbox transmission of one-level driving mechanism and has loaded.So, a main reducing gear must be set after speed changer, the moments of torsion such as the transmission part of main reducing gear front such as gearbox are reduced, the size of gearbox, quality are reduced, handle laborsaving.Also can be by lower deduction as can be known, the output power of motor is certain, according to the formula W=M of power * V(power=moment of torsion * speed), after by main reducing gear transmission speed being lowered, can obtain higher output torque, thereby obtain larger driving force.The Main Function that this shows main reducing gear is that each gear that extends to as speed changer provides a common velocity ratio, reduces simultaneously moment of torsion.Main reducing gear also has another effect in addition, changes exactly the direction of power transmission; The output of speed changer is one, and and wheel must rotate around the transverse axis of vehicle around the moment of vertical axes, and this just need to have a device to change the transmission direction of power.
Main reducing gear comprises bevel gear drive and helical gear.On the ransaxle of motor lateral arrangement automobile, main reducing gear often adopts simple helical gear.Main reducing gear generally comprises the retarder wheel cover, by the drive link driving wheel that is connected with speed changer and the follower that is connected wheel cover and is connected with live axle.Follower generally comprises the gear body, the body outer circumferential face has the gear teeth, so a side of follower is furnished with universal joint toward contact, has groove in a side end face of body; The diapire of described groove is the plane, and sidewall and the diapire of groove are vertical.The follower of said structure can be finished the effect of the transmission of power.But the sidewall of follower body recess is vertical with diapire, and in the application of reality, the rib that the sidewall of groove and end face form tends to affect the assembling of universal joint, simultaneously, and so that structure is not compact yet.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of follower of automobile main reducer, and this follower can be avoided the inconvenience of universal joint assembling, also makes compact structure simultaneously.
The purpose of this utility model can realize by following technical proposal: a kind of follower of automobile main reducer, its fixed cover is located on the transmission shaft, follower comprises the gear body, outer circumferential face at the gear body has the gear teeth, the both ends of the surface of described gear body have annular groove, it is characterized in that, the diapire of described annular groove is parallel to the end face of gear body, and the perisporium of described annular groove tilts with respect to diapire.In assembling, because the perisporium of annular groove tilts with respect to diapire, the space of occupying of saying of annular groove increases, and facilitates like this assembling that is positioned at the parts such as follower one side universal joint.Simultaneously, the bottom of annular groove sidewall is to reduce with respect to the thickness of body perisporium, has guaranteed the original intensity of gear.
In the follower of above-mentioned automobile main reducer, the diapire of described annular groove is provided with attachment hole.Pass attachment hole by bolt follower and live axle are connected, strengthen the join strength of follower and live axle, and be convenient to the dismounting of follower.
In the follower of above-mentioned automobile main reducer, the described gear teeth are helical teeth.The engagement driving of follower is more steady.
Compared with prior art, the follower of a kind of automobile main reducer of the utility model, its fixed cover is located on the transmission shaft, follower comprises the gear body, outer circumferential face at the gear body has the gear teeth, the both ends of the surface of gear body have annular groove, and the diapire of described annular groove is parallel to the end face of gear body, and the perisporium of annular groove tilts with respect to diapire.In assembling, because the perisporium of annular groove tilts with respect to diapire, the space of occupying of saying of annular groove increases, and facilitates like this assembling that is positioned at the parts such as follower one side universal joint.Simultaneously, the bottom of annular groove sidewall is to reduce with respect to the thickness of body perisporium, has guaranteed the original intensity of gear.
