Embodiment
Below by specific embodiment, the utility model is described in further detail, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of output shaft clutch-type gearbox, comprise input shaft clutch 1, input shaft 2, input shaft first driving gear 3, input shaft second driving gear 4, input shaft reverse driving gear 6, jack shaft 8, the reverse idler gear 20 be arranged on jack shaft, output shaft, output shaft slide teeth wheels and reverse gear sliding gear 17, described output shaft slide teeth wheels are made up of output shaft first sliding gear 19 mutually linked and output shaft second sliding gear 18.
Input shaft is provided with input shaft clutch, for combining or cutting off engine power, input shaft is provided with input shaft first driving gear successively, input shaft second driving gear and input shaft reverse driving gear, described each output shaft sliding gear and reverse gear sliding gear are installed on output shaft leading portion, output shaft sliding gear and reverse gear sliding gear all realize shifting gears by mounting with selector fork, its innovation is: also comprise output shaft clutch 12 and output shaft clutch lock locking mechanism, this output shaft clutch is overrunning clutch, described output shaft is made up of output shaft leading portion 5 and output shaft back segment 13, in the space that the cylindrical of endoporus and output shaft back segment front portion that described output shaft clutch is placed in output shaft leading portion rear portion is formed, can this output shaft clutch in conjunction with time by the output shaft wedging of two sections, front and back.
The locking clutch cover internal spline that described output shaft clutch lock locking mechanism comprises output shaft leading portion spline 10, output shaft back segment spline 11, locking clutch cover 9 and is formed in locking clutch cover, described output shaft leading portion spline is formed on the periphery at output shaft leading portion rear portion, and described output shaft back segment spline is formed on the periphery of output shaft back segment front portion.
Also comprise reverse gear variable-speed shaft 16, locking clutch cover shifting shaft 15 and locking clutch cover return spring 14, described reverse gear variable-speed shaft drives the action of reverse gear sliding gear, described locking clutch cover shifting shaft drives the action of locking clutch cover, one end of locking clutch cover shifting shaft is relative with reverse gear variable-speed shaft, the other end of locking clutch cover shifting shaft is connected with locking clutch cover return spring, interlock between reverse gear variable-speed shaft and locking clutch cover shifting shaft and disengaging is realized by driving the selector fork on reverse gear variable-speed shaft, thus engage by the slip of locking clutch cover internal spline or throw off on output shaft leading portion spline and output shaft back segment spline, realize locking clutch cover and reverse gear sliding gear interlock and disengaging, and then power can pass on wheel when making to reverse gear.
Also comprise locking clutch cover live axle 7, this locking clutch cover drive shaft locking clutch cover shifting shaft action.
Described output shaft sliding gear and reverse gear sliding gear are all by realizing shifting gears with selector fork; Described output shaft clutch lock locking mechanism can link with reverse gear sliding gear, ensures that realization is reversed gear, and also can pass through driver's individual operation, and ensureing can locking output shaft clutch under other operating modes.
When vehicle is in forward travel state, input shaft clutch and output shaft clutch all combine, output shaft first sliding gear is engaged on input shaft first driving gear, input shaft driver output axle leading portion rotates, output shaft leading portion driver output axle back segment rotates, and engine power can output to wheel smoothly;
When vehicle is in gearshift condition, driver is separated input shaft clutch, wheel power oppositely can input to gearbox, at this moment due to the feature of output shaft clutch single-direction transmission, output shaft clutch is in separated state, and now, input shaft and output shaft leading portion are in the state of geo-stationary, output shaft sliding gear is realized and the engaging of input shaft on input shaft second driving gear by shift fork, completes smooth shift and operates;
When vehicle needs to retreat, input shaft clutch is separated, reverse gear sliding gear is engaged with reverse idler gear by shift fork, reverse idler gear is meshed with input shaft reverse driving gear, simultaneously, reverse gear variable-speed shaft and locking clutch cover shifting shaft are connected, make locking clutch cover by the locking clutch cover internal spline in it by output shaft leading portion and output shaft back segment locking to together with, realize the rotation of output shaft back segment.
An output shaft, by the output shaft structure in conventional transmissions being done to improve, is become two-part (i.e. output shaft leading portion and output shaft back segment), and add overrunning clutch between two-part output shaft by the utility model.Like this, when driver's gear shift operation cuts off motor, overrunning clutch on output shaft just can cut off on output shaft back segment from the power that wheel transmits, make the input shaft of speed changer and output shaft leading portion all unpowered, gear place under static state carries out gear shift, each power shift gear is free to carry out mounting and there will not be the phenomenon of beating tooth, again in conjunction with input shaft and output shaft clutch after gear mounting puts in place, vehicle is travelled according to new gear.
Because overrunning clutch has the feature of single-direction transmission, output shaft overrunning clutch is in bonding state at motor to during wheel outputting power, can ensure that vehicle is when advancing, power is delivered to output shaft leading portion from input shaft, then is delivered to output shaft back segment from output shaft leading portion.(as accompanying drawing 1)
When gear-change operation, driver cuts off engine power, input shaft clutch is separated, and input shaft does not have power to input, if at this moment do not have output shaft clutch, wheel power meeting back transfer is to gearbox, after adding output shaft clutch, output shaft clutch can cut off the power that wheel transmits automatically, makes output shaft leading portion not have power to input, facilitate driver to carry out gear-change operation, there will not be and beat tooth phenomenon.(as accompanying drawing 2)
Reverse gear operation time, due to output shaft being provided with overrunning clutch, clutch can be made to be in separated state, the power that reverses gear can not be transmitted to wheel.At this moment, output shaft clutch lock locking mechanism, by clutch locking, makes power directly be delivered to output shaft back segment from output shaft leading portion.(as accompanying drawing 3)
During vehicle descending, driver's individual operation locking clutch cover, locking output shaft leading portion and output shaft back segment, make vehicle have engine braking function.(as accompanying drawing 4)
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.
