Description

Output drive for a vehicle
Technical Field
The present invention relates to an output drive for a vehicle; in particular to a technology for directly fixing one of the output gears of the output gear set on the differential mechanism to achieve the functions of reducing volume, simplifying assembly, simplifying structure and the like.
Background
Transmissions for vehicles or electric vehicles, such as transmissions, gear sets for transmitting power, differentials, etc., for driving the vehicle forward, backward, etc., are well known. For example, taiwan 87217364, automobile transmission (i.e., US 6146306, AUTOMOBILE TRANSMISSION DEVICE), and patent are examples of typical embodiments.
The prior variable speed transmission system of the vehicle comprises manual, automatic, continuous variable speed transmission systems and other types; the power of the engine rotating shaft or the motor rotating shaft is transmitted to a power output shaft through a speed change control mechanism, a power input gear set assembled on the power input shaft, a (bevel gear) differential mechanism arranged on the power output shaft, a power output gear set and other devices, so that the vehicle can obtain motions with different speed change ratios.
Basically, the speed change control mechanism comprises a plurality of spring-like bodies and a control push cylinder which are respectively assembled in and out of the force input gear set; a worm wheel disc is braked to rotate by a manual or automatic speed change control motor, different balls (or push rods) are selectively driven to push the control push cylinder, so that the spring body and the input gear set form an engaged or disengaged state, the input gear set with different teeth numbers respectively drive the output gear set and the differential mechanism, and the output shaft generates different rotating speeds to drive the vehicle.
The prior art also discloses improved means for the assembly or composition of the various parts of the differential mechanism; for example, taiwan 104213496 patent application of differential mechanism structural improvement, 106203295 patent application of vehicle differential mechanism control system, 96201922 patent application of differential locking device, 92213712 patent application of differential device of vehicle gearbox, etc. provide possible embodiments.
One problem related to the structural design, operation and application of the vehicle transmission and differential device is that the combination of the differential mechanism and the output gear set in the prior art must use a plurality of parts such as buckles, bearings (e.g. balls, rolling pins, unidirectional thrust bearings …, etc.) and the like to keep the stability of the output power freely rotating, thus forming a long-term limitation to the form of the inherent transmission mechanism, and the conventional transmission and differential device usually has the situations of large volume, complex structure, troublesome assembly, time consumption and high cost; this is not desirable.
Typically, these references show the design of conventional transmission, differential arrangements in terms of construction and application in terms of vehicle systems. If the matching situation of the output transmission mechanism and the differential device is considered by the heavy design, the mechanism design is in accordance with the condition of simple structure, the structure is different from that of the prior art, and the operation and the power transmission are simpler and direct, so that the power transmission mode can be changed, and the device is different from the prior art; or further reduces the space volume occupied by the transmission and differential device (or the whole force-output transmission system), thereby not only relatively increasing the mobility and the configuration degree of the vehicle space, but also being beneficial to simplifying the assembly operation of personnel and improving the situations of complex, troublesome and time-consuming assembly of the existing structure, high cost and the like; these problems are not taught or specifically disclosed in the above references.

Detailed Description
Referring to fig. 1 and 2, the output transmission device for a vehicle of the present invention includes a combination of a rotation shaft 80 (or input shaft) and an output shaft 90 connected to a power source; the power source (not shown) may be a motor, internal combustion engine or engine type to cause the rotatable shaft 80 to generate rotational power in a counter-clockwise or clockwise direction.
The rotary shaft 80 is shown provided with a power input gearset 10 and a shift control portion 20. The input gearset 10 selects a three or four speed transmission; thus, the input gearset 10 includes at least the first through third input gears 11 through 13. The input gearset 10 and the shift control portion 20 are conventional and will not be described in detail.
With respect to the input gearset 10, the output shaft 90 is provided with an output gearset 60 and a differential mechanism 70, which together form the output transmission. And, the output gear set 60 is rotatably fitted to an output shaft 75 of the differential mechanism 70. Therefore, when the rotational power of the input shaft 80 is transmitted to the output gear set 60 through the input gear set 10, the output gear set 60 will transmit the differential mechanism 70 and the output shaft 75 to rotate, so that the output shaft 90 generates the rotation of the driving wheels with different rotation speeds.
In the embodiment shown, the output gear set 60 is also a three or four speed drive system having a plurality of output gears of different diameters, including first through third rotatable output gears 61 through 63, respectively engaged with the first through third input gears 11 through 13. A unidirectional bearing 45 is respectively arranged between the first and second output gears 61 and 62 and the second and third output gears 62 and 63; each of the output gears 61-63 is allowed to drive only the lower gear to drive the higher gear, but the higher gear cannot drive the lower gear.
Fig. 1, 2 also depict that the diameter of the first output gear 61 is greater than the diameter of the second output gear 62, the diameter of the second output gear 62 being greater than the diameter of the third output gear 63; the output gear set 60 includes a disk 64 and a gear portion 65 disposed on the disk 64.
The first output gear 61 and/or the second output gear 62 of the output gear set 60 are shown to form an assembly area 66 at a location remote from the gear portion 65, such that the first output gear 61 and the second output gear 62 are configured to mate with the bearing 40 (e.g., needle bearing or the like) to mount the combined output shaft 75.
In a possible embodiment, the assembly area 66 is provided with at least a first section 67 and a second section 68 of the protruding or connecting disc body 64; the (needle) bearing 40 is provided at a position between the first section 67 and the output shaft 75. And, a position between the second segment 68 of the first output gear 61 and the second output gear 62 is provided with a sub bearing 50, and a position between the second segment 68 of the second output gear 62 and the output shaft 75 is also provided with a sub bearing 50. The sub-bearing 50 may be a ball bearing or the like.
Therefore, the first output gear 61 and the second output gear 62 cooperate with the bearing 40 of the first section 67 and the auxiliary bearing 50 of the second section 68, so that the first output gear 61 and the second output gear 62 respectively establish at least two mechanisms of rotation supporting points, and the first output gear 61 and/or the second output gear 62 obtain a stable transmission effect.
Referring to fig. 3, in the preferred embodiment, the disc 64 of the smallest diameter output gear (i.e. the third output gear 63) is provided with a combination portion 69, so that the third output gear 63 can be directly fixed on the output shaft 75; the situation that the existing structure is complex, troublesome and time-consuming to assemble is improved.
In detail, the combining portion 69 of the third output gear 63 is configured as a keyhole structure capable of combining with the holder 55. And, the force-exerting shaft 75 is formed with a wing 76 of a protruding structure; the wing portion 76 of the output shaft 75 (or the differential mechanism 70) is also provided with a bolt hole structure of the combination portion 69 corresponding to the third output gear 63, so as to facilitate the structural configuration of the manual operation of the fastener 55 to directly and simply fix the third output gear 63 to the output shaft 75 (or the differential mechanism 70).
Typically, this force transmission for a vehicle includes the following advantages and considerations over the prior art:
1. the combined structure of the output gearset 60, differential mechanism 70, and output shaft 75 of the output drive has been heavily designed. For example, the output gear set 60 is provided with a disc body 64 and an assembling area 66, the assembling area 66 forms a first section 67 and a second section 68, the bearing 40 and the auxiliary bearing 50 are respectively configured, and a mechanism of at least two rotation supporting points is established, so that the power transmission of the first output gear 61 and the second output gear 62 is stabilized; the third output gear 63 is provided with a combination portion 69, and the differential mechanism 70 forms a wing portion 76 and a combination portion 79, which are engaged with the retainer 55, and the like, which are significantly different from the conventional art.
2. In particular, the cooperation of the third output gear 63 (or the combination portion 69 thereof), the differential mechanism 70 (or the wing portions 76 and the combination portion 79 thereof) allows the person to directly cooperate with the combined action of the fastener 55 under the condition that the mechanism design thereof conforms to the simplified structure, not only the operation and the construction thereof are different from those of the conventional users, but also the operation and the power transmission thereof are simpler and more direct, and the power transmission mode thereof is changed; in contrast, the space volume occupied by the transmission and differential device (or the whole force-output transmission system) is further reduced, the movable allocation degree of the vehicle space is relatively increased, the assembly operation of personnel is simplified, and the situations of complex, troublesome and time-consuming assembly of the existing structure, high cost and the like are improved.
Therefore, the present invention provides an effective force transmission device for a vehicle, which has a space pattern different from that of the prior art and has incomparable advantages in the prior art.
However, the foregoing description is only one example of the present invention and is not intended to limit the scope of the present invention, i.e. all equivalent changes and modifications that are made according to the claims of the present invention are covered by the claims of the present invention.
