Abstract
The utility model relates to a novel test beam apparatus suitable for the test of an engine pedestal, including a beam trunk. An integral beam is employed for an engine pedestal test; the beam trunk is provided with a trunk hitch point, a secondary hitch point and a beam branch point in consequence; the trunk hitch point is fixedly provided on a test pedestal beam mounting rack; a 64 needle engine ECU mounting seat, an oil pump, a storage battery igniting switch, a main relay, an oil pump relay and a plug joint of a fuse box are separated from the trunk hitch point; the wire length is the distance from the plug members to the trunk hitch point; a power ground terminal and a fault diagnosis port are separated from the secondary hitch point; the beam branch point is arranged over the engine; an igniting system, each component plug joint and each electrical ground terminal of an oil injection system, an execution system and a control system are separated from the beam branch point; and the wire length is the distance from the plug members to the beam branch point. The utility model is characterized in that the structure is compact, the design is reasonable, and the required beam length can be effectively shortened, which is convenient for installation and plugging.
Description
Technical field
The utility model relates to a kind of wire harness, is a kind of device of the novel novel test wire harness that is applicable to engine bench test specifically.
Background technology
At present, when each engine producer carries out the engine bench test test, adopt the structure of car load wire harness, the plug connector of wire harness is many more, is installed in to seem on the stand that comparison disorderly; Particularly the test of new product engine is the electrical schematic diagram that provides according to coupling company, adopt stand wire harness similar to transform mostly with it temporarily, when process of the test breaks down, the investigation process because of the influence that will reject associated components develop quite loaded down with trivial details, failure cause is difficult for finding, under the malfunction elimination efficient.
Summary of the invention
The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, a kind of compact conformation, reasonable in design is provided, can effectively shorten required wire harness length, be convenient to install and peg graft the device of the distinct novel test wire harness that is applicable to engine bench test of fixing a breakdown.
In order to achieve the above object, the technical solution adopted in the utility model is: to a threst stand, adopt a whole wire harness, on the wire harness trunk, be disposed with the trunk hitch point, secondary hitch point and harness branch point, described trunk hitch point is fixed on the test-bed wire harness erecting frame, isolate 64 pin Engine ECU mount pads from the trunk hitch point, oil pump, storage battery and ignition switch, main relay, the connection-peg of FP Fuel Pump Relay and fuse box, wire length is the distance of each plug connector to the trunk hitch point, the place isolates Power Groud end and self-diagnosis of trouble fracture at described secondary hitch point, described harness branch point is arranged at the engine top, isolate igniting system from the harness branch point, oil spout system, execution system and control are each components and parts connection-peg and hold electronically that wire length is the distance of each plug connector to harness branch point.
The utility model has the advantages that:
1. compact conformation, reasonable in design, the engine bench test experiment wire harness behind the design improvement install on stand succinctly, make things convenient for, reliably, applicability is strong, and volume is small and exquisite, is convenient to store;
2. distinct convenient when engine carries out the malfunction investigation, be convenient to find failure cause;
3. wire harness is along the tendency of engine, and the flexible length of each connector matches with the distance of pegging graft, and the test wire harness of Suo Duaning is convenient to management simultaneously.
Description of drawings
Fig. 1 is the utility model structural representation;
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model is to a threst stand, adopt a whole wire harness, on the wire harness trunk, be disposed with trunk hitch point 1, secondary hitch point 2 and harness branch point 3, described trunk hitch point 1 is fixed on the test-bed wire harness erecting frame, isolate 64 pin Engine ECU mount pads from trunk hitch point 1, oil pump, storage battery and ignition switch, main relay, the connection-peg of FP Fuel Pump Relay and fuse box, wire length is the distance of each plug connector to trunk hitch point 1,2 places isolate Power Groud end and self-diagnosis of trouble fracture at described secondary hitch point, described harness branch point 3 is arranged at the engine top, isolate igniting system from harness branch point 3, oil spout system, execution system and control are each components and parts connection-peg and hold electronically that wire length is the distance of each plug connector to harness branch point 3.
Engine bench test test wire harness of the present utility model is to a threst stand, adopts a whole wire harness, is disposed with trunk hitch point 1, secondary hitch point 2 and harness branch point 3 on the wire harness trunk; Trunk hitch point 1 is fixed on the test-bed wire harness erecting frame, isolate the connection-peg of 64 pin Engine ECU mount pads, oil pump, storage battery and ignition switch, main relay, FP Fuel Pump Relay and fuse box from trunk hitch point 1, wire length is the distance of each plug connector to trunk hitch point 1; 2 places isolate Power Groud end and fault diagnosis mouth at secondary hitch point; Harness branch point 3 is arranged at the engine top, herein as the reference point that arrives each sensor connection-peg distance of engine, can make the stand wire harness invest the engine top equably, isolate igniting system from harness branch point 3 and (comprise the 2-3 ignition coil, the 1-4 ignition coil), oil spout system (comprising atomizer 1-4), carry out system and (comprise throttle position sensor, idle device and temperature, pressure transducer) and control system (comprise speed probe, detonation sensor, phase detector, front and back lambda sensors etc.) each components and parts connection-peg and end electronically, wire length is the distance of each plug connector to harness branch point 3.In this wire harness, the car load wire harness has been carried out the principle classification, rejected the connector harmless, shortened the connection distance with engine test, and in product, reserved inserted terminal to what homologous ray different type of machines limb definition there are differences, so that be applicable to different type of machines; The joint contact that must guarantee speed probe in use is good, avoids being subjected to the interference of other components and parts, because whether the working condition of other components and parts controlled by it.
