Description
Technical field：
The invention belongs to gearbox field, it is related to a kind of lorry gearbox, it is especially a kind of to carry centre brake and take
The multi-function variable-speed device of power device, occasion is prepared for lorry.
Background technology：
Speed changer is to lean on several gears to different drive ratios to realize changing torque and rotating speed, mainly by gear drive
Deceleration, increase torque effect.Two gears are meshed, and one tooth of driving gear promotes one tooth of driven gear, such as actively small
The number of teeth of gear is 8, and the number of teeth of driven gear wheel is 16, then pinion rotation 1 is enclosed, and gear wheel can only turn over half-turn, so one
Gear drive can just be reached reduces the effect of rotating speed.Meanwhile, the active force on two gear teeth contact surfaces is equal, root
Understand that under conditions of active force is equal, little gear radius is small, and torque is small according to the principle of " active force multiplies radius equal to torque ",
Gear wheel radius is big, and torque is also big, therefore, in little gear drive gear wheel, the rotating speed of gear wheel can be both reduced, again can be with
Increase the torque of gear wheel.The radius of actual gear and its number of teeth are a proportional relations, therefore, if disregard be driven
Frictional resistance in journey, the then multiple of the multiple of canine tooth wheel speed reduction, that is, torque increase.Make to realize that vehicle is actual
With the change torque and chronotropic action that are required under operating mode, speed changer must be made up of the multipair gear of different drive ratios.When a pair
During gear transmission power, other engagements that are out of gear.Pickup truck and the gearbox of dump truck matching are general in the market
For 5+1 keeps off gearbox, this gearbox can meet the requirement of vehicle dynamic property under general use condition.When automobile is full
When carrying even overload, travel on the field road in the larger mountain highway of the gradient and rural area, the phenomenon being short of power easily occur,
Easily there is landslide, security performance is relatively low, and brake is the chief component of auto brake system, its general principle is to utilize
Fixed original paper therein and the phase mutual friction for rotating original paper, the angular speed for making rotate element by frictional force is reduced, so as to reach
Automobile driving speed is reduced up to the purpose of parking, brake can be divided into wheel drag and center by the difference of its installation position
The major class of brake two, the rotation original paper of wheel drag is arranged on wheel, and its braking moment directly acts on wheel, center system
The rotate element of dynamic device is arranged on the power transmission shaft of automotive transmission, and its braking moment passes to car again by power transmission shaft and drive axle
On wheel, typically it is widely used on car, if centre brake, power takeoff are combined with speed changer and can solve ramp and be short of power
Caused Landslide Problems, effectively improve pickup truck and dump truck security performance.In the prior art, Chinese patent
CN102678889A discloses a kind of speed changer for pickup truck, including main speed-changing mechanism case and secondary gear case, main
Gear tank shell is connected with auxiliary transmission housing, and main-gear box mechanism case is provided with five forward and one reverses gear, secondary
Gear case is provided with a double reduction mechanism, and high to low gear rocking arm is provided with main speed-changing mechanism case, and its is easy to operate, total gear
Digit increases, output power increase, but parking braking effect on driving birds is not good, it is impossible to ensure ramp parking safety.
The content of the invention：
It is an object of the invention to the shortcoming for overcoming prior art to exist, seek design one kind with centre brake and take
