Abstract
The utility model relates to a high-power novel automobile power taking off, which comprises a pneumatic fork shifting mechanism 2, an input gear 10, an output axle 16 and a spline sleeve 15 provided with an inner spline 17. The input gear is sleeved on the output axle. A fork shifting bayonet 14 is arranged on the outer periphery of the spline sleeve. The input gear 10 adopts a double-linked gear, the front part of which has a gear 8 matching with the output gear of a speed variator, and the rear part of the input gear has a spline 13 matched with the inner spline of the spline sleeve. A spline 18 matching with the spline sleeve is also arranged at the middle part of the output axle 16. The spline 13 arranged on the output axle is arranged adjacent to the spline 18 on the output axle, and the spline sleeve 15 is sleeved on the spline on the output axle, and the spline is shifted by the pneumatic fork shifting mechanism to complete the on gear or off gear operation. The outer gear of a speed variator and the input gear of the power taking off which are meshed for a long term can not be damaged because of the gear on or gear off, the mode number of the spline is less, the circumferential pitch is small and the gear is complete by a plurality of gears, thereby being uneasy to be damaged when being geared on or geared off, thus the service life is long, and the higher power can be transferred.
Description
Technical field
The utility model relates to a kind of structure of automobile power takeoff, the novel power takeoff of a kind of high-powered automobiles.
Background technology
The automobile power takeoff is to take out the device that part power comes equipment such as driven wheel oil pump, vacuum pump from Automotive transmission, is used to reequip special-use vehicles such as dumping car, wheel crane.Present domestic large-tonnage automobile power takeoff (horsepower output is greater than 20KW), its structure all are to drive shift fork by pneumatic or manual declutch shift shaft, and the input gear of promotion power takeoff output gear direct and Automotive transmission performs or be out of supply.Because transmitted power is bigger, the modulus that therefore transmits gear is big, and the circular pitch of gear is also big, is easy to generate bump in the input gear of power takeoff and Automotive transmission output gear directly perform engagement process, and the output gear of Automotive transmission easily is damaged.
Summary of the invention
The utility model is intended to propose a kind ofly performing or be difficult for the structure of the power takeoff of damage car gearbox output gear, the novel power takeoff of a kind of high-powered automobiles when out of supply.
The novel power takeoff of this high-powered automobiles comprises air fork mechanism, input gear and output shaft, and input gear is enclosed within on the output shaft.It also comprises a spline housing that female splines is arranged, and a shift fork bayonet socket is arranged on the excircle of spline housing.Described input gear is a duplex gear, its anterior gear for matching with the gearbox output gear, the spline of its rear portion for matching with the female splines of spline housing, also there is a spline that matches with spline housing at the middle part of described output shaft, input gear is enclosed within the front portion of output shaft, spline on the input gear is adjacent with the spline on the output shaft, and spline housing is enclosed within on the spline on the output shaft, and the shift fork in the air fork mechanism snaps in the shift fork bayonet socket on the spline housing periphery.
When the novel power takeoff of this high-powered automobiles was installed on the automobile, the output gear of Automotive transmission was meshed with the input gear of the novel power takeoff of high-powered automobiles.When performing, mechanism stirs spline housing forward by air fork, and the forebody of spline housing is enclosed within on the spline at input gear rear portion, and spline housing latter half of still is enclosed within on the spline of output shaft, input gear promptly by spline housing with transmission of power to output shaft.When out of supply, mechanism stirs spline housing backward by air fork, and the spline on spline housing and the input gear is separated.Output shaft promptly stops operating.Because the input gear of gearbox output gear and the novel power takeoff of this high-powered automobiles meshes for a long time, do not need out of supply, not can because of perform, the out of supply damage.On the other hand, because the modulus of spline is little, circular pitch is little, is again multiple tooth engagement, thereby performs and not fragile when out of supply, long service life, and can transmit bigger power.
Description of drawings
Accompanying drawing 1 is the constructional drawing of the novel power takeoff of this high-powered automobiles;
Accompanying drawing 2 is the constructional drawing of input gear;
Accompanying drawing 3 is the constructional drawing of spline housing;
Accompanying drawing 4 is the constructional drawing of output shaft.
The specific embodiment
As shown in Figure 1, the novel power takeoff of this high-powered automobiles comprises air fork mechanism 2, input gear 10 and output shaft 16, and input gear is enclosed within on the output shaft.It also comprises a spline housing 15 (referring to Fig. 3) that female splines 17 is arranged, and a shift fork bayonet socket 14 is arranged on the excircle of spline housing.As shown in Figure 2, input gear 10 is a duplex gear, its anterior gear 8 for matching with the gearbox output gear, the spline 13 of its rear portion for matching with the female splines of spline housing.As shown in Figure 4, there is a spline that matches with spline housing 18 at the middle part of output shaft 16.As shown in Figure 1, input gear 10 is enclosed within the front portion of output shaft 16, spline 13 on the input gear is adjacent with spline 18 on the output shaft, and spline housing 15 is enclosed within on the spline on the output shaft, and the shift fork 3 in the air fork mechanism 2 snaps in the shift fork bayonet socket 14 on spline housing 15 peripheries.
1 is pressure spring among Fig. 1, provides propelling thrust for shifting fork mechanism when out of supply; 4 is casing, and 5 is the compressed air inlet, and 6 is bearing, and 7 is drive coupling, and 9 is bimetallic bush, and 11 is bearing, and 12 is the gearbox output gear.
