Abstract
The utility model particularly discloses a transmission of a direct connecting shaft of a horizontal single-cylinder engine, which is applied to the field of three-wheel trucks, single-cylinder low-speed cargo trucks and agricultural machinery. The novel transmission of the direct connecting shaft of the horizontal single-cylinder engine comprises a single-cylinder engine body, a crankshaft and a gearbox, and the single-cylinder engine body is transversely arranged. The novel transmission is characterized in that a flywheel casing is arranged on the outer side of a flywheel of the single-cylinder engine body, a positioning bearing block is disposed on the inner circumference of the flywheel casing, one side of the outer circumference of the flywheel casing is fixed onto the single-cylinder engine body, the other side of the outer circumference of the flywheel casing is connected with a clutch housing, the other end of the clutch housing is connected with the gearbox, a bearing hole is arranged on an end surface of the crankshaft, the outer end surface of the flywheel is connected with a clutch by a connecting plate, and an input shaft of the gearbox is fixed into the bearing hole on the crankshaft via the clutch. The transmission of the direct connecting shaft of the horizontal single-cylinder engine has the advantages that coaxiality of the crankshaft, the clutch and the gearbox is high, and the transmission is applicable to high-power transmission.
Description
Technical field
The utility model is applied in three wheeled motor vehicle, single cylinder low speed load-carrying vehicle and agricultural machinery field, is the direct-connected shaft drive of a kind of novel horizontal single cylinder engine specifically.
Background technology
The power transmission of China's three wheeled motor vehicle, single cylinder four-wheel automobile mainly is a belt-driving at present; It is simple in structure; Transmitted power receives the restriction of V-belt; Four Type B V-belt transferring power of the most employings of single cylinder engine three wheeled motor vehicle and low speed load-carrying vehicle at present, its rotative power is confined in the 13KW, and our present single cylinder engine power has surpassed 20KW.So strap drive can not give full play of the power delivery request of high-output engine; The direct-connected shaft drive structure of single cylinder engine progressively is used; And structure is various, but owing to reasons such as a lot of design defect, wherein the technical barrier is the right alignment problem that solves bent axle, power-transfer clutch and change speed gear box.
Summary of the invention
In order to remedy the deficiency of prior art, the utility model provides a kind of direct-connected shaft drive of high-performance novel horizontal single cylinder engine that is applicable to.
The utility model is realized through following technical scheme:
The direct-connected shaft drive of a kind of novel horizontal single cylinder engine; Comprise single cylinder engine body, bent axle and the change speed gear box of horizontal placement, its special character is: clutch bell of the flywheel arranged outside of said single cylinder engine body, and the internal diameter of clutch bell is provided with the fix shaft bearing; External diameter one side of clutch bell is fixed on the single cylinder engine body; The external diameter opposite side of clutch bell is connected with clutch case, and the other end of clutch case and change speed gear box be downlink connection mutually, and said crankshaft end-face is provided with bearing hole; The flywheel outer face is connected with power-transfer clutch through terminal pad, and the input shaft of said change speed gear box is fixed in the bearing hole on the bent axle through power-transfer clutch.
The technical scheme that the utility model adopts is: be employed in crankshaft end-face and be provided with bearing hole; Its input shaft with the parameter case is connected; Guarantee right alignment with this; And set gradually clutch bell in the flywheel outside and clutch case guarantees Joint strenght, be provided with terminal pad in the side of flywheel in addition and power-transfer clutch further guarantees Joint strenght.
Clutch bell and fix shaft bearing can be set together during this was novel, and horizontal single cylinder engine body and clutch bell also can be set together.
The utility model compared with prior art has: 1) clutch bell has guaranteed the right alignment with bent axle through fix shaft bearing seam location.2) clutch bell in the outside bolted connection, guaranteed the Joint strenght of clutch bell.3) the change speed gear box input shaft directly inserts in the crankshaft hole through power-transfer clutch, and body, main bearing cap, clutch bell support, clutch case, change speed gear box all adopt and be located by connecting, and have guaranteed right alignment, have shortened the connection distance.4) takeoff output of driving engine is abundant, and the predetermincd tension of no belt starts lighter.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the structural representation of the utility model;
Among the figure, 1, the single cylinder engine body, 2, bent axle, 3, the fix shaft bearing, 4, clutch bell, 5, flywheel, 6, terminal pad, 7, power-transfer clutch, 8, clutch case, 9, change speed gear box, 10, transmission shaft.
The specific embodiment
Accompanying drawing is a kind of specific embodiment of the utility model.This embodiment comprises single cylinder engine body 1, bent axle 2 and the change speed gear box 9 of horizontal placement; It is characterized in that: clutch bell 4 of flywheel 5 arranged outside of said single cylinder engine body 1; The internal diameter of clutch bell 4 is provided with fix shaft bearing 3, and external diameter one side of clutch bell is fixed on the single cylinder engine body 1, and the external diameter opposite side of clutch bell is connected with clutch case 8; The other end of clutch case 8 and change speed gear box 9 be downlink connection mutually; Said bent axle 2 end faces are provided with bearing hole, and the flywheel outer face is connected with power-transfer clutch 7 through terminal pad 6, and the input shaft of said change speed gear box 9 is fixed in the bearing hole on the bent axle through power-transfer clutch; Said clutch bell 4 is set together with fix shaft bearing 3, and said horizontal single cylinder engine body 1 is set together with clutch bell 4.
The technical scheme that the utility model adopts is: single cylinder engine body 1 is laterally placed; Increase a clutch bell 4 in flywheel 5 sides; And be fix shaft bearings 3 of these clutch bell 4 customized designs, this fix shaft bearing 3 has the effect of two aspects, and the one, the bearing seat of bent axle 2; The 2nd, as the alignment pin of clutch bell 4, so just solved the concentricity problem of bent axle 2, power-transfer clutch 7, change speed gear box 9.The clutch bell 4 of having good positioning is inboard and single cylinder engine body 1 bolt together at external diameter, has guaranteed the Joint strenght of clutch bell 4.Its outside is located by connecting with clutch case 8 again; Clutch case 8 is connected to form an integral body with change speed gear box 9 again; Bent axle 2 end face machining bearing holes; Flywheel 5 outer faces are adorned a terminal pad 6 and are connected with power-transfer clutch, and change speed gear box 9 input shafts insert in bent axle 2 holes by bearing fixing through power-transfer clutch,---terminal pad 6---power-transfer clutch 7---change speed gear box 9---transmission device that is outputed power by transmission shaft 10 again that forms by flywheel 5.
