(3) summary of the invention:
The object of the invention is to propose a kind of brake drum differential transfer case, forward and backward ransaxle can be given torque according to axle load pro rate, overcome the deficiency of traditional transfer case existence with this.
The brake drum differential transfer case of above-mentioned purpose can be realized, comprise transfer casing, described transfer casing is provided with power input shaft, propons output shaft and back axle output shaft, the gear of described power input shaft front end connecting engine, described propons output shaft connects propons, described back axle output shaft connects back axle, difference is provided with satellite differential in described transfer casing, described propons output shaft is one end output shaft of satellite differential, the other end output shaft of described satellite differential connects the brake drum of parking, described satellite differential is connected by gear drive with between power input shaft.
As long as apply certain braking force to brake drum during work, according to the principle of differential mechanism, can transmission of power to propons, if the resistance of front-wheel is greater than the power being applied to brake drum, then brake drum carries out slippage, can regulate the change of front and rear wheel displacement like this, reduces the wearing and tearing of tire.
A kind of structure of described satellite differential comprises planetary carrier, bevel planet gear and fan tooth, described bevel planet gear is located on planetary carrier, described fan tooth is installed on the output shaft of satellite differential two ends respectively, and both sides fan tooth engages with bevel planet gear simultaneously.
Described planetary carrier connects gear drive.
A kind of structure of described gear drive comprises shift gear, transition gear and driving gear, described shift gear and transition gear engage each other, described transition gear and driving gear engage each other, described shift gear slides and is located on power input shaft, and described driving gear and planetary carrier are coaxially connected.
Described back axle output shaft is coaxial with power input shaft, and the rear end of power input shaft is the output terminal of back axle output shaft.
Advantage of the present invention:
Brake drum differential transfer case of the present invention can make the component of whole transmission system extend working life, keeps the synchronism of forward and backward four-wheel, reduces the wearing and tearing brought tire, reduce the consume of power, improve economic benefit.
(4) accompanying drawing illustrates:
Fig. 1 is the structural representation of one embodiment of the present invention.
Figure number identifies: 1, transfer casing 2, power input shaft 3, propons output shaft; 4, back axle output shaft 5, planetary carrier 6, bevel planet gear 7, fan tooth; 8, shift gear; 9, transition gear 10, driving gear 11, brake drum 12, driving lever 13, jack shaft.
(5) embodiment:
Technical solution of the present invention the most applicable use 130 transfer case has been transformed, and is described further technological scheme of the present invention below in conjunction with accompanying drawing:
Brake drum differential transfer case of the present invention is primarily of transfer casing 1, power input shaft 2, propons output shaft 3, back axle output shaft 4 and the gear train assembly formation being located at transfer casing 1 inside, the gear of described power input shaft 2 front end (in Fig. 1 right side) connecting engine, described propons output shaft 3 connects propons, and described back axle output shaft 4 connects back axle.
Described back axle output shaft 4 is coaxial with power input shaft 2, and the rear end (on the left of in Fig. 1) of power input shaft 2 is the output terminal of back axle output shaft 4, and the front and back ends of power input shaft 2 all installs connecting flange, as shown in Figure 1.
Described gear train assembly is made up of gear drive and satellite differential, one end output shaft of described satellite differential is right side in propons output shaft 3(Fig. 1), satellite differential the other end output shaft connects the brake drum 11 of parking, and connecting flange is installed in propons output shaft 3 front end; Described gear drive is made up of shift gear 8, transition gear 9 and driving gear 10, described shift gear 8 to be slidably mounted on power input shaft 2 and to be connected with the driving lever 12 be installed on transfer casing 1, described transition gear 9 is fixedly mounted with jack shaft 13, under the effect of driving lever 12, shift gear 8 and transition gear 9 can depart from and engage or engage; Described satellite differential comprises planetary carrier 5, bevel planet gear 6 and fan tooth 7, described planetary carrier 5 is installed by bearing and is realized revolution, described bevel planet gear 6 is located on planetary carrier 5, described fan tooth 7 is installed on the output shaft at satellite differential two ends respectively, and both sides fan tooth 7 engages with bevel planet gear 6 simultaneously; Described driving gear 10 is coaxially fixedly mounted with planetary carrier 5 and engages with transition gear 9, as shown in Figure 1.
Using method of the present invention:
1, during normal vehicle operation, handle driving lever 12 and make shift gear 8 and transition gear 9 off-gear, engine power is passed to back axle through back axle output shaft 4, and the travelling state of vehicle is rear wheel drive.
2, during the forward and backward driving of vehicle needs, handling driving lever 12 makes shift gear 8 engage with transition gear 9, execute the certain braking force of 11 applyings according to running condition to brake drum, engine power is passed to propons through propons output shaft 3 simultaneously, and the travelling state of vehicle is that front and rear wheel drives.
3, in front and rear wheel driving process, if the resistance of front-wheel is greater than the power being applied to brake drum 11, then the brake shoe of brake drum 11 skids, thus regulates the change of front and rear wheel displacement, reduces the wearing and tearing of tire.
